Answer: The molar mass of the unknown protein is 
Explanation:
To calculate the concentration of solute, we use the equation for osmotic pressure, which is:

Or,

where,
= osmotic pressure of the solution = 2.45 torr
i = Van't hoff factor = 1 (for non-electrolytes)
Mass of solute (protein) = 5.87 mg = 5870 g (Conversion factor: 1 g = 1000 mg)
Volume of solution = 10 mL
R = Gas constant = 
T = temperature of the solution = ![25^oC=[273+25]=298K](https://tex.z-dn.net/?f=25%5EoC%3D%5B273%2B25%5D%3D298K)
Putting values in above equation, we get:

Hence, the molar mass of the protein is 
Answer:
The change was physical, meaning it went from liquid to solid, or the other way around.

I will state the electronegativities of each element.
Ca = 1.00
F = 3.98
H = 2.20
P = 2.19
Na = 0.93
The highest electronegative element is F (Fluorine).
